In a linoleumcutter, an elongated blade a preferred form of linoleum cutter macarrying member having a blade receiving comprise a blade carryingmember 2, whicopening extending lengthwise thereof, may conveniently be1n the form of a casts aeed handles on said. member, means for ing ofsuitable shape, having an operatin c amping the blade in position insaid openhandle 3 by which the same may be pushe ing, and guiding meanson said Amember forwardly duringthe cutting operation. The .adapted toengagey the linoleum to be cut,

' member 2 may so be provided with a supi substantially as clesc'ribed.y

clamping the blade in position in said opening, means engaging a backedge of the blade for adjusting the position of the blade in theopening, and a projecting handle on said blade to facilitate positioningthereof, substantially as described.

4. In a linoleum cutter, a blade receiving member having a kerf formedtherein and intersecting the lower face thereof, means operable in onedirection for clamping a blade in position in said kerf, and meansoperable at substantially right angles to said first mentioned means foradjusting the posi-` tion of the blade in said kerf, substantially asdescribed. L

5. In a linoleum cutter, a blade carrying member having a linoleumengaging face provided with a projecting guide rib, there being a bladereceiving opening intersecting said face, a blade in said opening havinga horizontally extending handle portion and a vertically extendingcutting portion and means for clamping the blade in position in saidopening, substantially as described.

6. In a linoleum cutter, a blade carrier having a longitudinallyextending kerf adapted to receive and support the blade of a standardlinoleum knife, and means for mamtaining a standard linoleum knife inoperative position in said ker, substantially as described.

7. In a linoleum cutter, a blade carrier, an operating handle projectingtherefrom, and means for clamping a standard linoleum knife in operativerelation to said carrier, substantially as described.

8. In a linoleum cutter, a blade carrier of generally elongated formhaving a longitudinally extending kerf formed therein and intersectingthe bottom face and one end of the carrier only, a linoleum knife havingits blade inserted within said kerf and havlng its handle portion`substantially in longitudinal alignment with the carrier, and means forclamping said blade in position in the kerf, substantially as described.

9. In a linoleum cutter, a blade carrier of generally elongated formhaving a longitudinally extending kerf Aformed therein and intersectingthe bottom face `and one end of the carrier only, a linoleum knifehaving its blade inserted within said kerf and having its handle portionsubstantially in longitudinal alignment with said carrier, and means forclam ing said blade in position in the kerf, sai carrier having guidingmeans projecting therefrom adjacent one side of and substantiallyparallel to the kerf for engaging one edge of the material being cut,substantially as described.

10. In a linoleum cutter, a blade carrier of generally elongated formhaving a longitudinally extendingkerf formed therein and intersectingthe bottom face and one end of the carrier only, a linoleum knife havingits blade inserted Within said kerf and having its handle portionsubstantially in longitudinal alignment with the carrier, and means forclamping said blade in position in the kerf,`said carrier having a pairof operating handles formed thereon, one of said handles being adjacenteach end of the carrier, substantiallly as described.

11. In a linoleum cutter, a blade carrier of generally elongated formhaving a longitudinally extending kerf formed therein and intersectingthe bottom face and one end of the carrier only, a linoleum knife havingits blade inserted within said kerf and having its handle portionsubstantially in longitudinal alignment with the carrier, means forclampingsaid blade in position in the kerf, and other means operable inthe plane of the kerf for adjusting the position of said blade,substantially as described.

12. In a linoleum cutter, a blade receiving member having a bladereceiving opening therein, a blade having a projecting handle, means forholding said blade in position in said opening with said handleprojecting into operative position, and a projecting shoulder on saidmember adapted to engage one edge of the material being cut for guidingthe movement of the cutter during the cutting operation, substantiallyas described.

In testlmony whereof I have hereunto set my hand.
